I would be careful about putting added oils in their food...there are a couple of threads on YT about members wondering if the extra oils caused upset stomaches or pancreantitus.
If you have him on a quality food his coat should show it. If he is dry it could be because the winter air is cry. I did have the vet tell me to get DermCaps from Petco for my Riley who had dry, itchy skin right after we got him from the breeder and after about 3 doses he was fine...it was a regulated dose and very short term. I think sometimes they go through the itchy stage when transitioning from the puppy coat to the adult coat too. |
